Hi all some good tyings there, I have not had time to finish tying some up and it is unlikely i'll get chance. I was going down the same lines as Mike but using a flouro yellow cock hacle tip (very fiddly trimming them). I have prepared some but never managed time to tie thanks mainly to central heating, dishwashers, confusers and some other issues.
Any way less of the rambling, one thing crossed my mind when preparing the paddles, even fine hackles are relatively rigid and I wonder if trying to tie in a paddle might make the fly spin in the water, is this a case where the suggestion of a paddle might be more effective than an exact imitation.
